Lump Under the Chin and Dizzy Spells While Eating

The dizzy spells and lying down mid-meal are the bigger concern and deserve a vet visit soon. Possible causes include pain in the mouth or throat, a swollen lymph node or salivary gland under the chin, or less commonly heart or neurological problems.
Ask your vet to examine the lump and his mouth, and to listen to his heart. A needle sample of the lump can tell whether it's a lymph node, salivary gland or something else.
This is general information, not a diagnosis. Please follow your own vet's advice.
